Abstract

A direct air capture system for use in a body of water that has waves with wave motion. The system includes at least one module exposed to the waves. The relative motion between the module and the waves to draws air into the module. The system removes carbon dioxide from the air using a moisture swing absorbent to remove the carbon dioxide from the air. The removed carbon dioxide can be used for various purposes.
